The Bosch PVA-4CR12 controller is the central paging manager for the PAVIRO system providing all the audio processing, supervision and control functions for a complete PAVIRO voice alarm and paging system.
Eight local audio inputs can be switched to four audio outputs and there is a two channel message manager.
One PVA-4CR12 controller supports up to 16 call stations and 492 paging zones and one controller can handle up to 2000 W loudspeaker load.
The controller is equipped with 12 zones, 18 GPIs and 19 GPOs. Additional zones and power can be added by using up to 20 external routers and 40 amplifiers with each 2 500 W.
Featuring:
Low power consumption in standby mode
Extreme flexibility
Excellent sound quality >106 dB s/n ratio
Up to 85 minutes internal digital message storage
The zone indicator lights on the front indicate the current status of every zone:
Green: Zone in use for non emergency purpose
Red: Zone in use for emergency purpose
Yellow: Zone fault detected
Off: Zone in idle condition
Audio 8 audio inputs, 4 audio outputs
